As you can see, there are a huge number of resources devoted to the Periodic System of Chemical Elements. Some of them are simple and simple, they make it possible to make only the most necessary inquiries. Others will read a lecture to you (in a female and male voice – to choose from), and video clips will be shown, and a database will be provided…
After displaying the entire table on the screen and admiring the color variety of cells, you need to click on the symbol of a specific element – and you can get more detailed information. It can be atomic number, atomic mass, atomic dimensions, oxidation degrees, density, melting point, boiling point, appearance, ionization energy, electronic formula, date of discovery of the element, crystal lattice parameters, the most important compounds, electrochemical potential, etc. etc.Looking through the variants of the Periodic Table presented on the Internet, we not only noted the completeness of the information, but also the design of the tables, and the ease of working with them. We have classified all the tables found in the network:
By target audience: tables for primary school students, regular school tables, as well as tables for students and researchers. For example: Periodic table of chemical elements for children. This is a kind, funny and witty Periodic Table for children. Despite the playful style of presentation (for example, the names of elements are presented using rebuses), it contains a sufficient set of factual information about common chemical elements.
By language: Russian-speaking, English-speaking, multilingual (with a choice of language). For example, the frequently visited site Periodic Table of the Elements (www.vebelements.com ) originally from Los Alamos.
According to the completeness of the presentation:
brief and voluminous. For example, on the website http://www.medkurs.ru information is displayed on topics ranging from the main stages of the development of chemistry, from the basic concepts of chemistry to the description of specific elements of the periodic table, including the Periodic Law, the general characteristics of individual groups of elements, many laws, chemical formulas and equations, and much more.
By design: classic, original (wooden, video table, HTML and FLASH versions), splash tables (on a mobile phone, on a desktop PC). For example, The Wooden Periodic Table contains information about chemical elements in wooden boxes that you can open and see what simple substances of many chemical elements look like.
By authorship: the authors of the spreadsheets are schoolchildren, students, scientists, research institutes and laboratories. For example: the author of the Periodic System resource is the Institute of Biology of the Karelian Scientific Center of the Russian Academy of Sciences. And the periodic system from the electronic textbook for schoolchildren, the author of which is Alexander Viktorovich Manuilov, is Novosibirsk State University.
By content: scientific and humorous. For example: The Periodic Table of Rejected Elements by Michael Gerber and Jonathan Schwarz or S.V. Emtsov’s joke_table.
We have reviewed a large number of Internet resources and made conclusions about the information provided to users of the Worldwide System:
The most detailed information is presented on the websites about the life and work of D.I. Mendeleev. It contains both biographical information about the life of the Great Chemist and interesting facts from his life. The main disadvantage is that many sites repeat the same information. The problem is also that there is no compiled information on the right topic on the sites.
Quite a lot of information in Internet resources can be found about the Periodic system of chemical elements of D.I. Mendeleev. In our opinion, the disadvantage of websites is often that with a very beautiful visual design, rather scarce information prevails and vice versa – there is a lot of information, and it is difficult to read it because of bright colors or dark background. In addition, many sites that contain information of interest to the user are in a foreign language. This is understandable, because the structure of the Russian segment of the Internet began to form in 1992, and educational portals even later.
Therefore, in the coming years there is something to work on for both professionals and novice users of the Network.
Work on creating your own version of the electronic periodic table.
Analyzing the information resources of the Internet, we increasingly came to the idea of creating our own version of the periodic table “Periodic system of D.I. Mendeleev”. Not to compete with professional programmers, web designers or research laboratories. And in order to repeat the educational material on the topic “Periodic law and periodic system of D.I. Mendeleev” once again, to learn new facts about chemical elements, and, finally, to provide the chemistry cabinet with a new electronic didactic manual.
To create our electronic product, we chose the Power Point environment and the option of an electronic mini-encyclopedia. The final version of the encyclopedia includes: 222 slides, 110 articles, 102 illustrations and more than 1300 hyperlinks. The periodic system works interactively. Clicking on the symbol of an element opens a page that shows the name of the element, its quantitative characteristics and hyperlinks, through which you can get information about the history of the discovery of the element, the etymology of its name, the content in nature and photos of the simple substance of this chemical element. A separate hyperlink opens an article with encyclopedic information about the element.
The encyclopedia is very convenient to use. Intuitive interface, multimedia, end-to-end navigation and encyclopedic informativeness make it an indispensable assistant for teachers and students. The first version of the table was presented at the Regional Festival of Educational Projects and received applications from chemistry teachers to copy the didactic manual.
This work has prospects for development and improvement both in terms of content (quantitative side) and design.
Summing up, I would like to note not only the theoretical, but also the practical value of our work. Based on the results of the study, we have compiled:
List of sites with spreadsheets “Periodic system of D.I. Mendeleev”.
Comparative tables about Internet resources on this issue.
Presentation “Internet Resources about the Great Law”
Author’s version of the spreadsheet.
If we return to the title of our work, which we formulated in the form of a question: “Why do we need another table?”, then we will answer:
Familiarity with electronic periodic systems hosted on the Internet shows that today there is no table that would satisfy all the requirements of users.
So, there are ways to improve electronic versions. In addition, information about new elements is emerging, digital photography and video are developing, new information and interesting facts are being extracted from archives. Therefore, the work on the study and improvement of Internet resources about D.I. Mendeleev and his Periodic System can be continued and make its feasible contribution.
Of course, we understand that in order to create the best electronic version of the Periodic System, not only knowledge of the historiography of the issue and the chemistry of elements is needed, but also knowledge of the basics of programming, the laws of virtual space and much more that we have to learn as students. But we are sure that the experience of creating this textbook has not only expanded our knowledge about D.I. Mendeleev and his great discovery, but also helped us to chart our course in the sea of Internet information resources.
